BMC Urol 2023; 23:154. [PMID: 37789333 PMCID: PMC10546657 DOI: 10.1186/s12894-023-01327-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Accepted: 09/17/2023] [Indexed: 10/05/2023] Open
Abstract
BACKGROUND Patients with benign prostatic hyperplasia (BPH) receive α-blockers as first-line therapy to treat lower urinary tract symptoms; however, some individuals still experience residual storage symptoms. Antimuscarinics, β3-agonists, and desmopressin are effective add-on medications. Nevertheless, there is currently no evidence for the appropriate choice of the first add-on medication. This systematic review aimed to investigate the clinical benefits of antimuscarinics, β3-agonists, and desmopressin, in addition to α-blockers, for persistent storage symptoms in BPH patients. METHODS A comprehensive literature search of randomized controlled trials (RCTs) comparing the efficacy of different add-on medications in BPH patients with persistent storage symptoms despite α-blocker treatment was conducted. Clinical outcomes included the International Prostate Symptom Score (IPSS), IPSS storage subscore, nocturia, micturition, and urgency. A network meta-analysis was performed to estimate the effect size. Surface under cumulative ranking curves (SUCRAs) were used to rank the included treatments for each outcome. RESULTS A total of 15 RCTs were identified. Add-on imidafenacin and mirabegron resulted in significant improvement in all outcomes assessed. Other add-on medications such as desmopressin, tolterodine, solifenacin, fesoterodine, and propiverine showed positive benefits for most, but not all, outcomes. Based on the SUCRA rankings, add-on desmopressin was the best-ranked treatment for IPSS and nocturia, and add-on imidafenacin was the best for the IPSS storage subscore and micturition. CONCLUSIONS BPH patients presenting with persistent storage symptoms despite α-blocker administration are recommended to include additional treatment. Desmopressin and imidafenacin may be considered high-priority add-on treatments because of their superior efficacy compared with other medications.

Abstract
Urinary incontinence is common after spinal cord injury (SCI) due to loss of supraspinal coordination and unabated reflexes in both autonomic and somatic nervous systems; if unchecked, these disturbances can become life-threatening. This manuscript will review normal anatomy and physiology of the urinary system and discuss pathophysiology secondary to SCI. This includes a discussion of autonomic dysreflexia, as well as its diagnosis and management. The kidneys and the ureters, representing the upper urinary tract system, can be at risk related to dyssynergy between the urethral sphincters and high pressures that lead to potential vesicoureteral reflux, urinary tract infections, and calculi associated with neurogenic lower urinary tract dysfunction (NLUTD). Recent guidelines for diagnosis, evaluation, treatment and follow up of the neurogenic bladder will be reviewed and options provided for risk stratification and management. Mechanical, pharmacological, neurolysis and surgical management will be discussed.

Abstract
BACKGROUND To evaluate the drug prescription patterns for men diagnosed with benign prostatic hyperplasia (BPH) in Korea. METHODS We extracted the data of 3% of the national patient samples including men aged ≥ 40 years between 2012 and 2017 from the Health Insurance Review and Assessment database and investigated the drugs prescribed for men with the BPH code N40. Men with a diagnosis of BPH but not receiving treatment were excluded. The primary outcome was the drugs prescribed and the changes in drug prescription pattern over 6 years for men first diagnosed with BPH. RESULTS Alpha blockers were the most commonly prescribed drugs in men with BPH, and tamsulosin was the most common. The proportion of prescriptions increased steadily. The number of prescriptions for anticholinergics (ACH) increased, but decreased with the start of mirabegron prescriptions in 2015. Prescriptions of mirabegron are increasing rapidly and replacing ACH. Based on the prescription pattern by drug category, alpha blocker monotherapy decreased, whereas combination therapies such as alpha blocker + 5-alpha-reductase inhibitors (5ARI), and alpha blocker + 5ARI + ACH increased steadily. As for the number of prescriptions by drug ingredient, tamsulosin monotherapy was the most common, and the combination therapy of tamsulosin and mirabegron increased. CONCLUSION Alpha blockers were the most commonly prescribed drug for men first diagnosed with BPH in Korea from 2012 to 2017, and tamsulosin was the most common alpha blocker. Prescriptions of combination therapy and mirabegron are gradually increasing.

Efficacy and safety of tamsulosin vs its combination with mirabegron in the management of lower urinary tract non-neurogenic overactive bladder symptoms (OABS) because of Benign Prostatic Enlargement (BPE)-An open label randomised controlled clinical study. Int J Clin Pract 2021; 75:e14184. [PMID: 33780106 DOI: 10.1111/ijcp.14184] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Revised: 03/22/2021] [Accepted: 03/25/2021] [Indexed: 11/30/2022] Open
Abstract
PURPOSE The efficacy and safety of βeta-3 agonists (Mirabegron 50 mg) have been sparingly assessed in the published English literature. We aim to do an efficacy-safety analysis of Mirabegron-Tamsulosin combination therapy vs tamsulosin-placebo monotherapy in a select subset of medication virgin Benign Prostatic Enlargement (BPE) patients with coexisting predominant non-neurogenic overactive bladder symptoms (OABS). METHODS After prior written informed consent and IEC, 80 patients of uncomplicated BPE with coexisting non-neurogenic OABS and IPSS of >7 without contraindications to drug therapy were computer randomised/allocated to receive either[50 mg Mirabegron plus Tamsulosin 0.4 mg (Intervention arm-I)]or [Tamsulosin 0.4 mg plus capsule lactobacillus (Comparator arm-II)] once daily for 8 weeks. Efficacy was evaluated using the OABS Score (OABSS), mean change in nocturnal frequency (NF), PVR and IPSS, while safety was assessed by recording treatment emergent adverse events (TEAE). Follow-up visits were performed at second, fourth and eighth week. RESULTS Patient data in both groups were generally comparable with the exception of NF and IPSS storage sub score (IPSS-ss). Significant improvements were visualised in the eighth week primary endpoint total OABS sub score (OABSS-ss) in the combination group (P < .001).Similar significant improvements were seen with most secondary parameters such as the mean change in NF, IPSS, IPSS-ss, OABS-ss, voided volume, Qmax, and Quality of life index (QOL) (P < .001). No significant increase in PVR was observed in the Mirabegron arm and no patient developed urinary retention. The TEAE were minor, self-limiting and managed symptomatically without drug discontinuity. CONCLUSION Mirabegron can be significantly efficacious and safe in ameliorating non-neurogenic OABS induced by BPE vs placebo by initiating combination therapy from the start as opposed to the usual 'add on therapy' protocol. This combination appeared to be superior in terms of overall safety, minimal side effects, better compliance and tolerability vs Tamsulosin monotherapy in select BPE patients with predominant non-neurogenic OABS.

Concentration-dependent alpha 1-Adrenoceptor Antagonism and Inhibition of Neurogenic Smooth Muscle Contraction by Mirabegron in the Human Prostate. Front Pharmacol 2021; 12:666047.

Abstract
Introduction: Mirabegron is available for treatment of storage symptoms in overactive bladder, which may be improved by β3-adrenoceptor-induced bladder smooth muscle relaxation. In addition to storage symptoms, lower urinary tract symptoms in men include obstructive symptoms attributed to benign prostatic hyperplasia, caused by increased prostate smooth muscle tone and prostate enlargement. In contrast to the bladder and storage symptoms, effects of mirabegron on prostate smooth muscle contraction and obstructive symptoms are poorly understood. Evidence from non-human smooth muscle suggested antagonism of α1-adrenoceptors as an important off-target effect of mirabegron. As α1-adrenergic contraction is crucial in pathophysiology and medical treatment of obstructive symptoms, we here examined effects of mirabegron on contractions of human prostate tissues and on proliferation of prostate stromal cells. Methods: Contractions were induced in an organ bath. Effects of mirabegron on proliferation, viability, and cAMP levels in cultured stromal cells were examined by EdU assays, CCK-8 assays and enzyme-linked immunosorbent assay. Results: Mirabegron in concentrations of 5 and 10 μM, but not 1 µM inhibited electric field stimulation-induced contractions of human prostate tissues. Mirabegron in concentrations of 5 and 10 µM shifted concentration response curves for noradrenaline-, methoxamine- and phenylephrine-induced contractions to the right, including recovery of contractions at high concentrations of α1-adrenergic agonists, increased EC50 values, but unchanged Emax values. Rightshifts of noradrenaline concentration response curves and inhibition of EFS-induced contractions were resistant to L-748,337, l-NAME, and BPIPP. 1 µM mirabegron was without effect on α1-adrenergic contractions. Endothelin-1- and U46619-induced contractions were not affected or only inhibited to neglectable extent. Effects of mirabegron (0.5–10 µM) on proliferation and viability of stromal cells were neglectable or small, reaching maximum decreases of 8% in proliferation assays and 17% in viability assays. Mirabegron did not induce detectable increases of cAMP levels in cultured stromal cells. Conclusion: Mirabegron inhibits neurogenic and α1-adrenergic human prostate smooth muscle contractions. This inhibition may be based on antagonism of α1-adrenoceptors by mirabegron, and does not include activation of β3-adrenoceptors and requires concentrations ranging 50-100fold higher than plasma concentrations reported from normal dosing. Non-adrenergic contractions and proliferation of prostate stromal cells are not inhibited by mirabegron.

Abstract
PURPOSE OF REVIEW To review the efficacy and safety of mirabegron in men with overactive bladder (OAB) and benign prostatic hyperplasia (BPH). RECENT FINDINGS Numerous studies have shown mirabegron to be efficacious and safe in treating symptoms of OAB. More recent studies evaluating the use of mirabegron in men with OAB and BPH have also shown the medication to be effective with few adverse side effects when used as monotherapy or in combination therapy. Mirabegron is an effective and safe treatment for men with OAB and BPH.

Beyond Antimuscarinics: A Review of Pharmacological and Interventional Options for Overactive Bladder Management in Men. Eur Urol 2021; 79:492-504. [PMID: 33402296 DOI: 10.1016/j.eururo.2020.12.032] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2020] [Accepted: 12/17/2020] [Indexed: 12/20/2022]
Abstract
CONTEXT The role of overactive bladder (OAB) treatment in women beyond antimuscarinics has been evaluated extensively. Beta-3 agonists, botulinum toxin-A (BTX-A), and nerve stimulation are indicated in these patients. However, data on male patients in this clinical scenario are scarce. OBJECTIVE The aim of this systematic review was to evaluate the evidence on treatment options beyond antimuscarinics in men with OAB. EVIDENCE ACQUISITION A search of PubMed, EMBASE, Scopus, Web of science, Cochrane Central Register of Controlled Trials, and Cochrane Central Database of Systematic Reviews databases was performed for relevant articles published between January 2000 and October 2020, using the following Medical Subject Headings: "male/man," "LUTS," "overactive bladder," "storage symptoms," "urgency," "nocturia," "incontinence," "beta-3 agonist," "PDE-5 inhibitors," "botulinum toxin," "sacral nerve stimulation/neurostimulation," "percutaneous/transcutaneous tibial nerve stimulation," "PTENS," and "combination therapy." Evidence acquisition was performed according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. PROSPERO registration number is CRD42020201223. EVIDENCE SYNTHESIS Overall, 24 studies were retrieved. In male OAB, mirabegron (MIRA) is the most intensively investigated pharmacological option. A pooled analysis of five randomized clinical trials (RCTs), including 1187 patients, concluded that MIRA 50 mg was associated with a greater reduction in frequency versus placebo (-0.37, 95% confidence interval [CI]: -0.74, -0.01, p < 0.05). A pooled analysis of three RCTs, including 1317 male patients, has also shown that the addition of MIRA 50 mg in men receiving the α1-blocker tamsulosin improved the mean number of micturitions per day (-0.27, 95% CI: -0.46 to -0.09, p < 0.05), urgency episodes (-0.50, 95% CI: -0.77 to -0.22, p < 0.05), total OAB symptom score (-0.66, 95% CI: -1.00 to -0.38, p < 0.05), and mean volume voided (+10.76 ml, 95% CI: 4.87-16.64, p < 0.05). MIRA treatment is well tolerated in men. Other pharmacological treatment options, such as phosphodiesterase-5 (PDE-5) inhibitors, should be considered investigational. BTX-A seems to be effective as third-line treatment in male OAB patients. A higher rate of intermittent self-catheterization (5-42%) is observed in male than in female patients. Data on nerve stimulation are scarce. CONCLUSIONS MIRA has the most robust data in terms of safety and efficacy in this patient population. Preliminary data in men suggest that BTX-A is indicated as an interventional treatment. Evidence for PDE-5 inhibitors and nerve stimulation is too limited to provide recommendations. Future studies in this population should aim to better define the best treatment sequence and to identify predictors for treatment response and failure, to determine a therapeutic approach tailored to patients' characteristics. PATIENT SUMMARY Overactive bladder is highly prevalent in men. Mirabegron 50 mg is the treatment option supported by the highest level of evidence when antimuscarinics failed. Botulinum toxin A injections seems to be an effective treatment as interventional option. Roles of nerve stimulation and phosphodiesterase inhibitors in male OAB patients are still to be defined.

Abstract
PURPOSE To investigate the efficacy and safety of mirabegron versus solifenacin as add-on for persistent OAB symptoms after tamsulosin monotherapy in men with probable BPO. PATIENTS AND METHODS This prospective randomized single-blind study was conducted on patients with persistent OAB symptoms after at least 12 weeks of tamsulosin 0.4 mg. The patients were randomized into group A in which mirabegron (50 mg once daily) was added and group B in which solifenacin (5 mg once daily) was added. Before and 12 weeks after addition of either drugs, we assessed the efficacy of the treatment using the OABSS, IPSS, Q max, MVV/mic and PVR. RESULTS Ninety two men were included in this study (46 patients in each group). All the study parameters were significantly improved after the 12-week treatment period in both groups except mean PVR which showed non-significant change in group A and a significant change in group B despite of being clinically irrelevant with only one case of acute urine retention. Overall, no significant difference has been observed between both groups after 12 weeks of treatment regarding all studied parameters except PVR. The incidence of side effects in group A was 10.9% versus 26.1% in group B. Main side effects included dry mouth in 2.2% and 8.7% and constipation in 2.2% and 6.5% in group A and B, respectively. CONCLUSION Our results indicate that the addition of either mirabegron or solifenacin to patients with persistent OAB symptoms after tamsulosin monotherapy has significant efficacy in controlling these symptoms. The adequate balance between efficacy and tolerability reported in this study with mirabegron may result in better QOL and overall patient satisfaction if compared with antimuscarinics.

Abstract
AIMS To assess the efficacy of salt reduction for improving nocturia in patients with high salt intake. METHODS Changes in lower urinary symptoms and frequency volume chart by salt intake (men: 8 g/day; women: ≥7 g/day) were analyzed in this prospective study. Patients were instructed to use a brochure for salt intake restriction via interview once every four weeks. The daily salt intake was estimated by using spot urine samples. RESULTS Two-hundred twenty-three (69.5%) patients were successful in reducing their daily salt intake (S group), whereas 98 (30.5%) patients failed to reduce their salt intake (F group). In the S group, nocturia improved from 2.3 ± 0.9 to 1.4 ± 1.0, and nocturnal polyuria index (NPi) improved from 30.2 ± 7.5 to 27.7 ± 7.3% (P < 0.001). In the Core Lower Urinary Tract Symptom Score (CLSS) of the S group, Q3 (urgency) improved from 1.0 ± 1.0 to 0.9 ± 1.0 (P = 0.001); Q1 (diurnal frequency) (P < 0.001), and Q2 (nocturia) also improved (P < 0.001). Moreover, the quality of life parameter improved significantly (P < 0.001). The patients in the F group did not have improvements in any symptom during the study period. CONCLUSIONS Patients with nocturia who also have high salt intake should be advised to reduce their salt intake, as a lifestyle modification. Our results support the importance of randomized clinical trials with larger populations and the appropriate inclusion/exclusion criteria to conclude the clinical usefulness of salt reduction in this patient cohort.

Lee YK, Kuo HC. Safety and therapeutic efficacy of mirabegron 25 mg in older patients with overactive bladder and multiple comorbidities. Geriatr Gerontol Int 2018; 18:1330-1333. [PMID: 29931793 DOI: 10.1111/ggi.13465] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2018] [Revised: 04/10/2018] [Accepted: 05/27/2018] [Indexed: 02/04/2023]
Abstract
AIM The present study assessed the therapeutic efficacy and safety of mirabegron 25 mg in older patients aged ≥80 years with overactive bladder and multiple comorbidities. METHODS Patients with overactive bladder were prospectively treated with 25 mg of mirabegron once daily. The patients were divided into a younger group (aged 40-60 years) and an older group (aged ≥80 years), and their underlying comorbidities were recorded. The primary efficacy end-point was the change in symptom score from baseline to the third month. Safety assessments included adverse events and post-void residual urine volume. RESULTS A total of 217 patients (younger, n = 62; older, n = 155) were included. The older patients had more comorbidities than the younger patients. Statistically significant improvements in the Quality of Life index and Patient Perception of Bladder Condition were noted in the younger patients from 1 month after treatment, whereas the International Prostate Symptom Score-Voiding subscore, International Prostate Symptom Score-Total, Quality of Life index, post-void residual urine volume and Patient Perception of Bladder Condition were all significantly decreased in the older patients after 3 months of treatment. The mean changes in the International Prostate Symptom Score-Voiding subscore, maximal flow rate, post-void residual urine volume, nocturia and Urgency Severity Score were significantly different between the two groups. The younger patients experienced more minor adverse events than the older patients (41.94% vs 24.62%) during treatment. Nevertheless, the adverse event rate was acceptably low in both groups. CONCLUSIONS Mirabegron 25 mg once daily is a safe and effective treatment for older patients with overactive bladder. Geriatr Gerontol Int 2018; 18: 1330-1333.

Liao CH, Kuo HC. Mirabegron 25 mg Monotherapy Is Safe but Less Effective in Male Patients With Overactive Bladder and Bladder Outlet Obstruction. Urology 2018; 117:115-119. [PMID: 29630956 DOI: 10.1016/j.urology.2018.03.038] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2017] [Revised: 01/02/2018] [Accepted: 03/22/2018] [Indexed: 02/02/2023]
Abstract
OBJECTIVE To compare the therapeutic efficacy and safety of mirabegron monotherapy in male patients with overactive bladder (OAB) with and without bladder outlet obstruction (BOO). MATERIALS AND METHODS Male patients with OAB aged ≥20 years, with or without BOO, receiving mirabegron 25 mg monotherapy once daily, were prospectively enrolled. The treatment results were assessed using global response assessment, international prostate symptom score and subscores, overactive bladder symptom score, patient perception on intensity of urgency scale, patient perception of bladder condition, and quality of life index at 1 and 3 months after treatment. RESULTS Of the 289 enrolled patients (mean age, 71.2 years), 207 did not have BOO (71.6%) and 82 had BOO (28.4%). The baseline OAB symptoms were similar between patients with and without BOO. After mirabegron treatment, the satisfactory rate (global response assessment score ≧1) were similar between those without BOO (61.3%) and with BOO (57.1%). The improvement of quality of life index and patient perception of bladder condition was also found in both groups. However, only patients without BOO had significantly improved international prostate symptom score and subscores, overactive bladder symptom score, and patient perception on intensity of urgency scale. Although most adverse events (AEs) were mild, patients with BOO had significantly higher AEs rate (18.6%) than those without BOO (8.2%, P = .026). CONCLUSION Mirabegron monotherapy in male patients with OAB and BOO was safe. However, the storage symptoms improvement was less in patients with BOO and AEs rate was higher.

[PMID: 29473309 PMCID: PMC7379193 DOI: 10.1111/luts.12218] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2017] [Revised: 12/15/2017] [Accepted: 01/11/2018] [Indexed: 11/29/2022]
Abstract
OBJECTIVE Mirabegron is widely considered as an effective and safe drug for patients with overactive bladder (OAB). However, there is no evidence regarding the efficacy of mirabegron in human T cell lymphotropic virus-1 (HTLV-1)-associated myelopathy/tropical spastic paraparesis (HAM/TSP) patients with OAB symptoms. The aim of the present study was to clarify the efficacy of mirabegron in HAM/TSP patients with OAB symptoms. METHODS The present study evaluated the efficacy of mirabegron treatment (50 mg, once daily) in nineteen HAM/TSP patients with OAB symptoms by assessing subjective symptoms using the overactive bladder symptom score (OABSS) and International Prostate Symptom Score (IPSS) before and 12 weeks after administration. Voided volume (VV), maximum flow rate (Qmax ), and post-void residual (PVR) urine volume were evaluated as objective symptoms. RESULTS Mirabegron treatment improved OABSS in terms of night-time frequency, urgency, and total score (P < .001). In addition, on the IPSS, mirabegron therapy improved urgency, nocturia, storage symptoms (Questions 2, 4 and 7 on the IPSS), as well as the total score (P < .001). The quality of life (QoL) on the IPSS also improved after treatment (P < .001). However, there were no significant changes in objective symptoms, as measured by VV, Qmax , and PVR, after treatment. One patient (5.3%) complained of dry mouth; because this adverse effect was very mild, the patient did not discontinue mirabegron. CONCLUSIONS Mirabegron administration improved subjective symptoms in HAM/TSP patients with neurogenic OAB.

Best practice in the management of storage symptoms in male lower urinary tract symptoms: a review of the evidence base. Ther Adv Urol 2017; 10:79-92.

Abstract
Storage lower urinary tract symptoms (LUTS) are characterized by an altered bladder sensation, increased daytime frequency, nocturia, urgency and urgency incontinence. Some evidence underlines the role of metabolic factors, pelvic ischemia, prostatic chronic inflammation and associated comorbidities in the pathophysiology of storage LUTS. A detailed evaluation of the severity of storage LUTS, and the concomitance of these symptoms with voiding and postmicturition symptoms, is mandatory for improving the diagnosis and personalizing treatment. A detailed medical history with comorbidities and associated risk factors, a physical examination, a comprehensive analysis of all the features of LUTS, including their impact on quality of life, and a frequency-volume chart (FVC) or bladder diary, are recommended for men with storage LUTS. Several drugs are available for the treatment of LUTS secondary to benign prostatic obstruction (BPO). Alpha-blockers (α-blockers), 5-α-reductase inhibitors and phosphodiesterase type 5 inhibitors are commonly used to manage storage LUTS occurring with voiding symptoms associated with BPO. Muscarinic receptor antagonists and Beta 3-agonists (β3-agonists) alone, or in combination with α-blockers, represent the gold standard of treatment in men with predominant storage LUTS. There is no specific recommendation regarding the best treatment options for storage LUTS after prostatic surgery.
